WALL-REGISTER.

SPECIFICATION forming part Of Letters Patent N0. 746,355, dated December8, 1903.

Application filed March 18 1903. Serial No. 148,344:- (No modelJ To allwhom it may concern.-

Be it known that I, LoUIs J. MUELLER, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements inWall-Registers, of which the following is a specification, referencebeing had to the accompanying drawings, forming a part thereof.

This invention relates particularly to that class of registers which aredesigned to be set in vertical wallsand which are provided with singlevalves ordampers. Its main object is to simplify and improve theconstruction and operation of registers of this class.

It consists in certain novel features of construction and in thepeculiar arrangement and combinations of parts hereinafter particularlydescribed and claimed.

In the accompanying drawings like letters designate the same parts inthe several figures.

Figure 1 is a front elevation of a wall-register, with a part brokenaway, embodying my improvements. Fig. 2 is a vertical crosssection ofthe same on the line 2 2, Fig. 1; and Fig. 3 is a horizontal section onthe line 3 3, Fig. 1, showing the damper operating and holding piece.

a designates the register-frame, which may be of any desired pattern. Itis provided with a front grille or grating b, which may be cast withsaid frame or made separately and rigidly secured therein in anysuitable manner.

This grating is preferably curved or inclined outwardly toward thebottom, as shown in Fig. 2, to form a more convenient foot-rest.

c is a valve or damper, which may be conveniently made of sheet metal.It is horizontally hinged at its upper edge in the frame a on a rod (1or in any other convenient way. The frame ais formed on the back sidearound the opening therein with a recess or rabbet, into which the valve0 fits when closed.

. e is an operating and holding piece attached to the valve or damper c.It preferably consists of a wire-spring loop secured at its ends in saidvalve or damper centrally near its hinge connection with the frame andcurved outwardly and upwardly therefrom. At its outer looped end it ishooked or bent into a handle or toe piece to facilitate opening andclosing the valve with the foot. This loop passes outwardly between andbinds-at its sides against parallel bars or friction-bearings ff withsufficient force to hold the valve or damper in any position to which itmay be adjusted. These friction-bearings may be formed with the frame aand grating 19 or attached to either or both of said parts. To increasethe elasticity or flexibility of the operating and holding loop 6, oneof its ends may be allowed lateral play in the valve 0, the other endbeing rigidly secured therein by riveting or otherwise.

It will be observed that the loop e does not project sufficiently fromtheregister-frame in any position of the valve to be in the way orobjectionable, while it affords an extremely "simple, eifective, andconvenient device for opening, closing, and adjusting the valve ordamper and also for holding it securely in any desired position.

Various changes in the minor details of construction and arrangement ofparts may be made within the principle and intended scope of theinvention.

1. In a wall-register the combination of a suitable frame providedadjacent to one edge with a bearing, and avalve or damper hinged at oneend adjacent to said bearing in said frame and provided with anoperating-piece which binds against said bearing with sufiicient forceto. hold said valve or damper in adjusted position, substantially asdescribed.

2. In a wall-register the combination of a suitable frame provided witha friction-hearing, a valve or damper hinged at one end in said frameand provided with a spring operating-piece rigidly attached thereto atits hinged end and binding against said bearing, substantially asdescribed.

3. In a wall-register the combination of a suitable frame havingopposing friction-bearings, and a valve or damper hinged in said frameand provided with an operating-piece consisting of a spring-loopattached to said valve or damper and binding against said bearings,substantially asdescribed.

4. In a wall-register the combination of a suitable frame provided withopposing parallel friction-bearings, and a valve or damper hinged insaid frame and having attached thereto a curved spring-loop which passesbetween and binds against said bearings, substantially as described.

5. In a wall-register the combination of a suitable frame provided witha front grating h aving parallel vertical friction-bearings, and a valveor damper horizontally hinged in the upper part of said frame and havingattached thereto a spring operating and holding loop which passesbetween and binds against said bearings, substantially as described.

6. In a wall-register the combination of a suitable frame provided witha front grating having near the top vertical friction-bearin gs, and avalve or damper horizontally hinged in the upper part of said frame andprovided LOUIS J. MUELLER.
